I doubt it. Making it 1.0 would be completely wrong. Beam is not finished. I don't know what @tdev is thinking.
Most likely 2.0 or 2.5. "Complete" games are usually at 3.0 or up. This is not totally true, it depends on the game.
So hyped for West coast, i don't even care on numbers or sounds and especially the covet sounds, which is rubbish.
Just because they change the sound provider doesn't mean they added sounds. Just means they laid the groundwork for sounds.
but that means that they are finally working on it with the old sound engine it was difficult to have decent sounds, but this engine will defenetly be easier to achive that and give more tools to modders
